To all whom t may concern.'

Be it known that I, HERBERT G. BEEDE, a citizen of the United States ofAmerica, and resident of Pawtucket, in the county of Providence andState of Rhode Island, have invented new and useful Improvements in R''gf Twisting or Spinning Devices, of which the "following isaspecification.

This invention concerns ring twisting or spinning mechanism and relatesmorepar'- ticularly toa ring and traveler of that type commonly employedin' the twisting and spinning of'relatively heavyy yarns or cords.Although the invention is primarily intended for twisting, itl may alsobe used for spinning certain materials, such as jute or linen,l and itsbroader application to both twisting and spinning is contemplated by theclaims.'

Inthe operation of the older type of twisting mechanism whichis welladapted for the twisting of line yarns, the vertical traveler employedis subjected during its movement both to the drag of the yarn and tocentrifugal action. Vith such an arrangement' a properly weightedtraveler tends to'balance about the lower flange of the 'ring under theopposing action of centrifugalforce andthe yarn-1 pull and under suchcircumstances any undue increase in speed-:results in increasedcentrifugal' force with' a corresponding increase in` frictional dragfof theV traveler upon the ring', while ad# ditional tension on the yarntends to dee crease such drag, ythe speed of revolution of the travelerbeing -thus automatically controlled. In" starting the machine theyarnpull is'relatively large, thus decreasing the' frictionaldrag'andpermitting the traveler quickly to come to normal speed, while instopping, the pull ofthe yarn is reduced substantially to zero andcentrifugal action serves quickly to bring the traveler to rest withoutoverrunning.V

In the devices disclosed inv patents to Herbert G. Be'ede Nos;1,075,004, October 7, 1913 and 1,174,961, March v14C, 191,6,yanvarrangement suitable for the twisting and spinning of heavy yarns orcords is disclosed in which the speed ofthe revolving ring or traveleris automatically controlled by centrifugal action' alone. Thearrangements disclosed in these patents serve to exertl av .varyingcentrifugall draguipon the' revolving ring 'directlyinfaccordance withvariations in' the speed of the latter, thus effectively controllingsu'ch speed during normal running' off in connection with twistingvor'spiniiingl de"- vices ofthe general type disclosedinthel aforesaidpatents, such' that the velocity-pri the 'revolvingring may bemadedep'end'ent imposed by4 the the yarn will strain, andv instopping,.the revolving ring" promptly andwithout runwill come to restning ahead.

The labove object maywell' be accom-,l

In the' drawings the numeral 1 indicates a portion of the rail of aspinning frame or twister, such rail being' provided with an openingfr'the reception of the stationary ring 2. This ring comprisesan'upstanding'` flange 3. a'substantially parallel upstanding' flange 4,and a downwardly directed? {iange 5, the two last-named fiangesbeing'substanL tia-lly in alignment and providingthe c' lindrical innersurface- 6, Within' the channel between the flanges 3 and 4:'arrar'lged. the revolving 'traveler ring comprisingithe cylindricalfringmember 7 and 'the' annule-'r'- 8, the members 7 and' 8 b'eing'suitably.

plate secured together as byfmeans efscreW-s 9.. The' member 7 isprovided upon'its exterior surface with a ball race groove 10 which-co'-operates with a complemental groove in'a ring 11,also seated within the'channel be'- tween the flanges 3, 4, andsecured to the provide anarrangement useful*- yarn, whereby' in s tartin'g,` not be subjectedtofundfi'eby way of example in theacange 3 by means of screws such as12. W'ithin the hall race thus provided are arranged ball bearings 13anc, if desired, the individual bearings may be held in spaced relationby means of a suitable cage 14 having slots or openings for thereception of the several balls. The traveler ring as thus arranged maybe rotated very easily within the stationary ring, while the bearingsfor such ring are well protected from dirt or fly.

Suitable yarn guides are provided in accordance with the number of yarnends to be twisted together. 1n the present instance, two such guidesare illustrated, these guides comprising the plates 15, 16 respectively,which rest upon the upper surface of the annular member 8, such platesbeing provided at opposite ends with radially elongate slots 17. Screws18 pass loosely through such slots and engage threaded openings in themember 8 whereby the plates 15, 16 are permitted to move slightly in aradial direction but are secured to the revolving ring for rotationtherewith. Depending from the inner edges of the respective plates 15,16 are the members 19, 20, constituting brake shoes for engagement withthe inner cylindrical surface 6 of the stationary ring 2. Mounted uponthe plates 15, 16 are yarn guide eyes 21, 22 respectively, plates 15,16, or, if desired, formed as separate elements suitably securedthereto. As

indicated in Fig. 1 the yarn Y passes through'the guide eye 21 fortwisting with a similar yarn (not shown) passing through eye 22, as suchyarns are wound upon the spindle. 1n the operation of the above device,it being assumed that the spindle is stationary, a considerable tensionor drag is placed upon the yarn Y as the spindlestarts to rotate, sothat if the guide eyes are not already in ositions corresponding to thatillustrated at the left of Fig. 2, they will immediately be pulledinwardly to occupy such a position. As thus positioned, the brakemembers 19, 20 are out of contact with the surface 6 of the stationaryring and thus the drag of the yarn may readily impart a rotatingmovement to the revolving ring about the axis of the spindle withouthaving to overcome any frictional resistance other than that of the ballbearings.r As the ring speeds up, centrifugal force tends to move theplates 15 and 16 with their brake shoes 19, 20 o-utwardly until suchshoes occupy positions such' as indicated at the right-hand side of Fig.Q. As thus arranged, the brake shoes, by contact with the surface 6,offer a certain amount of frictional resistance to the rotation of therevolving ring. This centrifugal action during normal operation variesin accordance with the speed of rotation of such eyes being integralwith thea the revolving traveler ring, while the drag of the yarn actsin opposition to centrifugal force, the two forces tending to balanceone another, so that the brake device thus provided tends automaticallyto retard the speed of rotation of the revolving ring. When the windingspindle S is stopped, the momentum of the relatively heavy revolvingtraveler ring with its brake devices tends to continue its rotatingmovement, and if such movement should continue for any appreciable timethere would be a tendency to tangle the several yarn ends which at thistime are free from any substantial tension. The removal of tension uponthe yarn ends however, permits centrifugal force to act withoutrestraint upon the plates 15 which thus move freely outwardly, bringingthe brake shoes 19, 20 firmly against the inner surface 6 of thestationary ring thereby imposing an effective braking action whichserves to bring the revolving ring to rest very quickly. lt will thus beevident that in starting, the drag upon the yarn is sufficient toovercome the action of the brake devices thus permitting the revolvingring to speed up rapidly, while in stopping, the cessation of drag uponthe yarn permits the full effect of centrifugal action to be applied tothe brake devices thus stopping the traveler quickly.

`While a specific arrangement for mounting the revolving traveler ringin the stationary ring has been illustrated herein, it is to beunderstood that in so' far as the automatic control of the action of therevolving ring is concerned, such precise arrangement is immaterialexcept in so far as it tends to reduce friction between the stationaryand rotating parts, thus making the brake device more sensitive inoperation than would be the case were the revolving ring less free tomove.
